    Abstract This study examined adaptation to work stress

    among public school teachers (n = 267). Regression

    analyses tested whether positive affect predicted successful

    and unsuccessful adaptation to stress (viz., resilience and

    burnout, respectively) after controlling for demographic

    characteristics and work stress. Positive affect was largely

    correlated with resilience (r = .65, p \ .001) and burnout(r = -.57, p \ .001). The regression of resilience showedthat positive affect had a direct effect (b = .66, p \ .001)and the total model explained 44 % of the variance (R2

    Change = 37 %). In the regression of burnout, positive

    affect also had a direct effect (b = -.41, p \ .001) and thetotal model explained 52 % of the variance (R2 Change =

    14 %). Further analyses found no significant interaction

    between work stress and positive affect, but revealed that

    positive affect completely mediated the effect of work

    stress on resilience. Results provide support for the

    broaden-and-build theory of positive emotions, particularly

    the theorys building and undoing effects.

    Introduction

    Studies have found that teachers are seriously affected by

    the stressfulness of their work environment (e.g., Dunham

    and Varma 1998; Travers and Cooper 1996; Zhang and

    Sapp 2008). Teaching is among the most stressful profes-

    sions with 42 % of teachers reporting high work stress and

    36 % feeling stressed all or most of the time (Smith et al.

    2000). Longitudinal evidence indicates that approximately

    95 % of teachers experience increasing levels of perceived

    work stress over time (Chan et al. 2010). Teachers face a

    variety of stressors in the workplace, such as excessive

    workload, changes in curriculum, disruptive students, lack

    of support from parents and the administration, conflicts

    with colleagues, increasingly strict standards of account-

    ability, and performance evaluations (Kyriacou 2001;

    Manthei et al. 1996; Montgomery and Rupp 2005).

    Constant exposure to high levels of work stress can

    disrupt teachers homeostasis, inhibiting their ability to

    cope effectively and maintain healthy functioning, and

    result in either diminished (i.e., establishing a lower level

    of homeostasis) or dysfunctional recovery (i.e., succumb-

    ing to the stressful situation and feeling defeated; Carver

    1998; Connor and Davidson 2003; OLeary and Ickovics

    1995). Persistent unsuccessful adaptation to stress con-

    tributes to the development of health problems such as the

    burnout syndrome (Bakker et al. 2000; Bellingrath et al.

    2009; Melchior et al. 2007; Wang 2005). Work stress and

    burnout among teachers have reached alarming levels,

    threatening the quality of the educational system and sub-

    sequent student achievement (e.g., Kyriacou 2001; Travers

    and Cooper 1996; Zhang and Sapp 2008). Difficult work-

    ing conditions and low teacher salaries (Macdonald 1999;

    Skaalvik and Skaalvik 2011) fuel psychosomatic symptoms

    and disorders related to burnout, all of which contribute to

  • teachers prematurely leaving the profession (Bauer et al.

    2006). It is estimated that 4050 % of new teachers leave

    the profession after only 3 years (Ingersoll and Smith

    2003), and over 90 % of new teachers are replacements

    for those who resigned for reasons other than retirement

    (Ingersoll 2002).

    Teacher burnout is characterized by three interrelated

    components: emotional exhaustion, depersonalization, and

    reduced personal accomplishment (Maslach et al. 1996,

    2001). Emotional exhaustion is the stress component and

    central quality of burnout, occurring when a teacher is

    extremely fatigued and feels overextended by work and

    drained of emotional and physical resources (Schwarzer

    and Hallum 2008). Depersonalization represents the inter-

    personal component and is described as feeling cynical,

    irritable, and negative towards others. Teachers are more

    likely to develop an indifferent or cynical attitude and

    detached response on the job when feeling emotionally

    exhausted and discouraged (Maslach et al. 2001). Finally,

    reduced personal accomplishmentthe self-evaluation

    componentincludes feelings of ineffectiveness and a lack

    of productivity and achievement at work; it is difficult to

    feel a sense of accomplishment at work when feeling

    emotionally exhausted and indifferent or cynical toward

    others (Maslach and Leiter 2008). Burned-out teachers

    typically report concurrent feelings of extreme fatigue

    (Schwarzer and Hallum 2008), cynicism and negativity

    toward others (Maslach et al. 2001), and a sense of despair

    and diminished achievement at work (Maslach and Leiter

    2008).

    Interestingly, not all teachers experience symptoms of

    burnout. Some teachers adapt successfully to stressful sit-

    uations and demonstrate resiliencethey perceive change

    and stressful situations as a challenge, maintain their

    commitment to teaching despite challenging conditions and

    recurring setbacks (Brunetti 2006), and perceive a sense of

    personal control in handling day-to-day events (Kobasa

    1979). Such adaptive outcomes from otherwise challenging

    conditions suggest that resilient teachers are able to cope

    with and persist in the face of adversity, balancing their

    internal needs and desires with those of their students and

    the context of the external environment. For example, Gu

    and Day (2007) explored the role of resilience in charac-

    terizing teacher effectiveness among 300 teachers

    throughout their careers, and found that resilient teachers

    sustain their motivation, commitment, and effectiveness

    despite the range of difficult experiences they encounter in

    their work environments. Similarly, a recent study of

    novice teachers working in stressful under-resourced public

    schools found that teacher effectiveness was predicted by

    individual traits such as perseverance, passion for long-

    term goals, and life satisfaction (Duckworth et al. 2009).

    These findings are consistent with a recent review on

    teacher resilience that identified having a positive attitude,

    self-efficacy, coping and teaching skills, professional

    reflection and growth, and self-care, as well as important

    contextual factors such as positive studentteacher rela-

    tionships, administrative support, and support from peers,

    colleagues, family, and friends as enabling teachers to

    thrive rather than just survive (Beltman et al. 2011). Fur-

    ther, the role of resilience in teacher effectiveness is con-

    sistent with the wider research literature that describes

    resilient characteristics as including goal setting, patience,

    faith, tolerance of negative affect, having close and secure

    relationships, possessing the ability to focus and think

    clearly, humor, and having a positive outlook even under

    negative circumstances (Connor and Davidson 2003).

    Research in positive psychology has demonstrated that

    positive affectivity plays a significant role in predicting

    whether an individual will successfully or unsuccessfully

    adapt to stressful situations (Danner et al. 2001; Duckworth

    et al. 2009; Lyubomirsky et al. 2005). A wide spectrum of

    empirical evidence documents the adaptive value of posi-

    tive affect in promoting resilience and successful adapta-

    tion to stress (e.g., Danner et al. 2001; Davis et al. 1998;

    Folkman and Moskowitz 2000). From a theoretical per-

    spective, Fredricksons broaden-and-build theory of posi-

    tive emotions posits that the experience of positive affect

    expands ones scope of attention and cognition, and thus

    enables more flexible and creative thinking (Fredrickson

    2004; Fredrickson and Joiner 2002; Isen and Daubman

    1984; Isen et al. 1987). The broadened cognition and

    engaged attitude, in turn, promotes successful adaptation to

    stress, and over time builds enduring psychosocial resour-

    ces (e.g., adaptive coping strategies, positive personal

    traits, and enhanced social support). These resources pro-

    mote resilience and prevent undesirable outcomes such as

    burnout (Fredrickson 2001, 2009; Fredrickson et al. 2003).

    In contrast, the theory also suggests that individuals who

    experience lower levels of positive affect tend to have

    narrowed mindsets during stressful situations; this response

    is due to the fight-or-flight reaction, which constricts ones

    cognitive capacity in order to expedite decision-making

    and immediately remove adversity. While this response

    may be critical in life-or-death situations, it is often mal-

    adaptive in situations that call for more time-consuming

    and thoughtful actions, especially against stressors that are

    constant and unrelenting such as those commonly reported

    by teachers. As a result, teachers who experience lower

    levels of positive affect are less likely to effectively cope

    with stress and more likely to express problems such as the

    burnout syndrome.

    Previous studies have examined the influence of positive

    affect on a variety of stress-related outcomes (e.g., Fred-

    rickson et al. 2000, 2003). For example, positive affect was

    found to have a direct effect on psychological functioning

    186 Motiv Emot (2013) 37:185193

  • (Nelson and Knight 2010), physiological health (Fred-

    rickson and Levenson 1998), and effectiveness of novice

    teachers in disadvantaged schools (Duckworth et al. 2009).

    In addition, researchers have also demonstrated that posi-

    tive affect interacts with stress and moderates its negative

    effect on health (Davis et al. 1998; Faulk et al. 2012; Ong

    et al. 2006) such that the impact of stress on health is

    reduced when ones positive affect is high. However, we

    have yet to find studies that have assessed the influence of

    positive affect on the relationships among work stress,

    burnout, and resilience with public school teachers.

    Therefore, the purpose of the present study was to examine

    whether positive affect predicted successful and unsuc-

    cessful adaptation in teaching (viz., resilience and burnout,

    respectively), while controlling for the effects of a variety

    of demographic characteristics and perceived work stress.

    It was hypothesized that positive affect would have a

    significant independent direct positive effect on resilience

    and a negative effect on burnout, above and beyond that of

    perceived work stress and demographic covariates. We also

    tested whether there was a significant interaction, or

    moderating effect, between perceived work stress and

    positive affect in predicting resilience and burnout; we

    hypothesized that positive affect would significantly

    interact with stress and moderate the influence of stress on

    resilience and burnout (i.e., as levels of stress increase,

    individuals with higher levels of positive affect will report

    lower levels of burnout and higher levels of resilience, in

    contrast to those with lower levels of positive affect).

    Results of this study could provide support for the broaden-

    and-build theory of positive emotions as an effective the-

    oretical framework for developing programs designed to

    help teachers maintain resilience and prevent burnout.

    Methods

    Participants and procedures

    Participants were obtained with assistance from a conve-

    nience sample of public school teachers in Texas identified

    as recipients of a prestigious Teaching Excellence Award

    granted by the alumni association of a large public uni-

    versity. Each teacher was sent a package via the United

    States Postal Service that contained a letter explaining the

    purpose of the study as well as six packets with copies of a

    self-report survey and stamped addressed envelopes for the

    convenient return of the completed surveys. A snowball

    sampling technique was used in which the award-winning

    teachers (n = 170) were instructed to complete one of the

    six surveys, and distribute the remaining five survey

    packets to fellow teachers who they believed represented a

    variety of teaching skills and years of experience. A deck

    of inspirational quote cards ($5 value) was included in each

    packet as a small incentive for participation. To further

    encourage participation, a stamped addressed postcard was

    also included to allow participants to be entered into a

    raffle drawing for a number of prizes, such as an auto-

    graphed university football ($100 value), a university

    t-shirt ($19 value), or a gift card ($15 value). One incentive

    prize was given for every 10 surveys that were received. To

    maintain participant anonymity, the survey instruments

    were anonymous and completed at participants discretion;

    the identifiable raffle postcards were mailed separately

    from the surveys.

    The final sample consisted of n = 267 public school

    teachers from 94 different zip codes across Texas, repre-

    senting a moderate response rate of 26 % (Alreck and

    Settle 2004). Approximately 75 % were female with a

    mean age of 45 years (ranging from 23 to 68 years); 86 %

    were White, 8 % Hispanic or Latino, 3 % African-Amer-

    ican, and less than 1 % each was Native-American or

    Asian-American. The majority were high school teachers

    (75 %), while others taught in middle (13 %) or elementary

    (12 %) school. Overall, the sample was highly experi-

    enced, with an average of 18 years of teaching experience.

    Most earned a bachelors degree (55 %), although 43 %

    held a masters degree, and 2 % had attained a doctorate

    degree. Approximately 22 % of these teachers (n = 58)

    were recipients of a prestigious Teaching Excellence

    Award from the university conducting the study.

    Measures

    The survey instrument assessed participant demographic

    characteristics, work stress, positive affect, resilience, and

    teacher burnout. A copy of the survey may be requested

    from the corresponding author.

    Demographics

    Participants were asked to report personal characteristics

    including age, gender, ethnicity, education level, grade

    level taught, years of teaching experience, and whether

    they had received a Teaching Excellence Award from the

    universitys alumni association.

    Work stress

    Perceived work stress was conceptualized as taxing work

    conditions that undermine adaptation, and was assessed

    using a modified version of the Teacher Stress Inventory

    (Fimian 1984). The original instrument was updated to

    include a broad range of potential stressors as well as an

    assessment of each stressors exposure and appraisal. The

    instrument assessed if participants had experienced 41

    Motiv Emot (2013) 37:185193 187

    123

  • commonly occurring stressful situations within the past

    year (0 = not experienced, 1 = experienced). Sample

    stressor items included not enough time to get things

    done, administration not supportive enough, class size

    or caseload is too big, tension with another teacher or

    administrator, and pressure to adhere to instructional

    planning guides. If the stressor had been experienced, the

    participant appraised how negative, undesirable, or

    upsetting the stressful situation was on a five-point scale

    ranging from 0 to 4 (not at all to extremely). To score each

    of the 41 items, the responses to the exposure and appraisal

    questions were multiplied. A final perceived work stress

    score was then calculated as the sum of the 41 (expo-

    sure 9 appraisal) items, with higher scores indicating

    greater levels of work stress. The instrument obtained a

    strong internal consistency (a = .92), and concurrentvalidity was confirmed by a significant correlation

    (r = .59, p \ .001) with the 4-item Perceived Stress Scale(PSS; Cohen et al. 1983).

    Positive affect

    Positive affect was operationalized as the individuals

    experience of general positive feelings that enhance adap-

    tation. This global measure of positive affect is reflective of

    ones general feelings and emotions, in contrast to emo-

    tional reactions in response to specific stimuli (Rottenberg

    2005). This conceptualization is in alignment with the

    research base that most often focuses on global positive

    affect without distinguishing between moods and emotions

    (Lyubomirsky et al. 2005). Positive affect was measured

    using a 19-item modified version of the Positive Activation

    subscale of the Positive and Negative Affect Schedule

    (PANAS; Watson et al. 1988). This modified measure

    consists of the original 10 items included in the PANAS plus

    9 additional positive emotions (viz., amused, calm, content,

    curious, happy, relaxed, relieved, satisfied, surprised) added

    by Tugade and Fredrickson (2004). On a five-point scale

    ranging from 1 to 5 (not at all to very much so), participants

    were asked to respond to the following instructions: This

    scale consists of a number of words that describe different

    feelings and emotions. Read each item and then indicate

    how you generally feel. The positive affect score was then

    calculated as the sum of the 19 items, with higher scores

    indicating greater positive affect. The internal consistency

    of the modified instrument was strong (a = .92).

    Resilience

    Participant resilience (i.e., successful adaptation to stress)

    was assessed using the 25-item ConnorDavidson Resil-

    ience Scale (CD-RISC; Connor and Davidson 2003). This

    instrument measured a variety of resilient characteristics

    that enable individuals to thrive in the face of adversity,

    such as goal setting, patience, faith, humor, and tolerance

    of negative affect, as well as the ability to perceive a

    challenge, make a commitment, and take control. On a

    five-point scale ranging from 0 to 4 (not true at all to true

    nearly all the time), participants responded to items

    including I believed I could achieve my goals, even if

    there were obstacles and under pressure, I stay focused

    and think clearly. The resilience score was calculated as

    the sum of the items, with higher scores indicating greater

    resilience. The CD-RISC instrument reported a strong

    (a = .89) internal consistency.

    Teacher burnout

    The Maslach Burnout Inventory-Educators Survey (MBI-

    ES) was used to assess teacher burnout (i.e., unsuccessful

    adaptation to stress; Maslach et al. 1996). The MBI-ES

    measures all three components of the burnout syndrome:

    emotional exhaustion (9 items), depersonalization (5

    items), and reduced personal accomplishment (8 items), on

    a seven-point scale ranging from 0 to 6 (never to every

    day). A sample emotional exhaustion item includes I feel

    emotionally drained from my work; a sample deperson-

    alization item includes I dont really care what happens to

    some students; and a sample reduced personal accom-

    plishment item (reverse-scored) includes I feel Im posi-

    tively influencing other peoples lives through my work.

    Total burnout was calculated as the sum of all three com-

    ponents, with higher scores indicating greater teacher

    burnout. The internal consistency of the MBI-ES instru-

    ment was strong (a = .93).

    Statistical analyses

    All analyses were conducted using the Statistical Package

    for the Social Sciences (SPSS) version 16. Years of

    teaching experience was retained as a continuous control

    variable; multiple-category demographic control variables

    were collapsed into binary values in order to construct

    appropriately-sized groups for analysis: award recipient

    (0 = did not receive a Teaching Excellence Award,

    1 = received an award), secondary school (0 = taught

    elementary school, 1 = taught middle/high school), female

    (0 = male, 1 = female), minority (0 = nonminority,

    1 = minority), and advanced degree (0 = bachelors

    degree, 1 = masters or doctorate).

    Hierarchical multiple regression analyses were used to

    examine the ability of positive affect to predict levels of

    resilience and teacher burnout, after controlling for the

    variance associated with the demographic variables and

    work stress. The interactive effects of work stress and

    positive affect on resilience and burnout were also

    188 Motiv Emot (2013) 37:185193

    123

  • examined. Due to the high correlation (r = .81) between

    age and years of teaching experience, age was excluded

    from the analyses. Preliminary analyses were conducted to

    ensure that statistical assumptions of power, normality,

    linearity, multicollinearity, independence, and homosce-

    dasticity were satisfied. Values of all continuous predictors

    were centered to prevent potential multicollinearity prob-

    lems (Aiken and West 1991).

    Results

    Table 1 displays the correlations, means, standard devia-

    tions, and range values for all study variables. Positive

    affect had a large positive correlation with resilience and a

    large negative correlation with teacher burnout, according

    to Cohens criteria (1988). The strongest association

    among the control variables was a moderate correlation

    between winning an award and years of teaching experi-

    ence. Additionally, teachers with an advanced degree had

    more years of teaching experience and were more likely to

    have won an award. Control variables were not strongly

    related to work stress, positive affect, resilience, or teacher

    burnout; although there were some significant correlations,

    they were small in size. More experienced and award

    winning teachers reported greater positive affect and less

    burnout. Award winning teachers also reported greater

    resilience and females reported greater work stress.

    Positive affect predicts successful adaptation to stress

    The six demographic variables (viz., years taught, award

    recipient, secondary school, female, minority, and

    advanced degree) were entered in Step 1, but did not sig-

    nificantly contribute to the variance in resilience (see

    Table 2). After entry of work stress in Step 2, the total

    variance explained by the model as a whole was 7 %, F (7,

    256) = 2.76, p \ .01. Work stress demonstrated a signifi-cant direct negative effect on resilience (b = -.17,p \ .01), explaining an additional 3 % of the variance inresilience, after controlling for the demographic variables,

    R2 Change = .03, F Change (1, 256) = 7.21, p \ .01.Upon entering positive affect in Step 3, the total variance

    explained by the model as a whole was 44 %, F (8,

    255) = 25.22, p \ .001. Positive affect explained anadditional 37 % of the variance in resilience, after con-

    trolling for the effects of the demographic variables and

    work stress, R2 Change = .37, F Change (1, 255) =

    169.73, p \ .001. In this equation, positive affect recordeda significant direct positive effect (b = .66, p \ .001), butwork stress became non-significant (b = .02, p [ .05).1

    1 Interestingly, the unexpected drop in the significance of work stress

    suggested that positive affect could be mediating the link between

    work stress and resilience. To analyze this model, we used Preacher

    and Hayes (2008) INDIRECT macro with the bootstrapping method

    to determine if positive affect actually mediated the relationship

    between work stress and resilience, while controlling for demographic

    covariates (viz., years taught, award recipient, secondary school,

    female, minority, and advanced degre). Results revealed significant

    direct paths between work stress and positive affect (b = -.09,p \ .001), and between positive affect and resilience (b = .66,p \ .001). After controlling for the effects of positive affect and theset of demographic controls, the direct relationship between work

    stress and resilience was nonsignificant (b = .01, p [ .05), indicatingthat positive affect fully mediated the link between work stress and

    resilience. The control variables had nonsignificant relationships with

    resilience, except for female (b = 2.50, p \ .05) which indicated thatfemale teachers reported greater resilience than males. The indirect

  • Holding all else constant, as positive affect increased by

    one standard deviation, resilience was estimated to increase

    by .66 standard deviation. To examine if positive affect had

    a moderating effect on the relationship between work stress

    and resilience, the interaction term work stress x positive

    affect was tested in Step 4 but was non-significant.

    Positive affect predicts unsuccessful adaptation to stress

    Initially, the effects of the demographics, work stress, and

    positive affect were calculated on each component of tea-

    cher burnout (viz., emotional exhaustion, depersonaliza-

    tion, and reduced personal accomplishment) as well as on

    total burnout (i.e., the sum of the three components). Given

    that the regression results for each component of the

    burnout syndrome were similar to those using a total score,

    only the results using the total burnout score are presented.

    The six demographic covariates were entered in Step 1,

    and significantly explained 8 % of the variance in burnout

    (see Table 3). After entry of perceived work stress in Step

    2, the total variance explained by the model as a whole was

    38 %, F (7, 255) = 22.35, p \ .001. Work stress demon-strated a significant direct positive effect on burnout

    (b = .57, p \ .001), explaining an additional 30 % of thevariance in burnout, after controlling for the demographic

    variables, R2 Change = .30, F Change (1, 255) = 123.10,

    p \ .001. Upon entering positive affect in Step 3, the total

    variance explained by the model as a whole was 52 %,

    F (8, 254) = 34.73, p \ .001. Positive affect explained anadditional 14 % of the variance in burnout, after control-

    ling for the effects of work stress and the demographic

    variables, R2 Change = .14, F Change (1, 254) = 75.62,

    p \ .001. In this equation, work stress and positive affectboth recorded significant direct effects; work stress had a

    positive effect (b = .45, p \ .001) while positive affecthad a negative effect (b = -.41, p \ .001). Holding allelse constant, as work stress increased by one standard

    deviation, burnout was estimated to increase by .45 stan-

    dard deviation. In contrast, as positive affect increased by

    one standard deviation, burnout was estimated to decrease

    by .41 standard deviation. To examine if positive affect had

    a moderating effect on the relationship between work stress

    and burnout, the interaction term work stress x positive

    affect was examined in Step 4 but was non-significant.

    Discussion

    Using survey data from a cross-sectional study design, we

    examined the influence of positive affect on successful and

    unsuccessful adaptation to perceived work stress (viz.,

    resilience and burnout, respectively) in a convenience

    sample of public school teachers in Texas. After control-

    ling for the effects of demographic characteristics and work

    stress, positive affect had a direct positive effect on resil-

    ience and a direct negative effect on burnout; further

    analysis indicated that positive affect completely mediated

    the relationship between work stress and resilience.

    The direct effect of positive affect on resilience sup-

    ported the value of positive affect in predicting successful

    adaptation to stress (Fredrickson and Losada 2005; Keyes

    2002). Specifically, our results indicated that higher scores

  • on positive affect were associated with higher scores on

    resilience. This finding supported the building effect of

    Fredricksons (2001) broaden-and-build theory of positive

    emotions, which suggests that experiences of positive

    affect build ones cognitive and behavioral resilience

    resources, and thereby help individuals more effectively

    manage stress and adaptively cope with adversity. Further,

    the non-significant interaction between work stress and

    positive affect indicated that the effect of stress on resil-

    ience did not depend on the teachers levels of positive

    affect. Our data instead revealed that the impact of work

    stress on resilience was fully mediated by positive affect,

    suggesting that teachers resilience was not directly deter-

    mined by work stress but rather indirectly via their positive

    affectivity (see Footnote 1); this supports previous work, as

    positive affect has been found to restore psychological

    resources and enhance well-being in the face of stress

    (Folkman 1997, 2008; Fredrickson et al. 2003). Thus, from

    a practical standpoint, we recommend that in addition to

    creating positive workplace conditions, interventions

    should also focus on individual stress management pro-

    grams that increase experiences of positive affect even

    amidst stressful working conditions (e.g., adoption and

    practice of adaptive coping strategies; mindfulness strate-

    gies) as a method to promote successful adaptation to

    adversity and enhance teacher resilience. Although hard-

    ships are inevitable, this strategy may be more effective

    than attempting to change environmental workplace

    stressors, considering that individual positive affect is more

    malleable and within ones locus of control, as opposed to

    stressful work conditions, which often are unavoidable and

    uncontrollable.

    With regard to teacher burnout and unsuccessful adap-

    tation to stress, the direct positive effect of stress on

    burnout suggested that teachers with higher levels of per-

    ceived work stress were more burned out, while the direct

    negative effect of positive affect on burnout suggested that

    teachers with higher levels of positive affect were less

    likely to experience burnout. The non-significant interac-

    tion, or moderation effect, between work stress and posi-

    tive affect indicated that the impact of work stress on

    teacher burnout was not dependent upon ones level of

    positive affect; this was an unexpected finding considering

    previous evidence behind the moderating influence of

    positive affect on stress (Davis et al. 1998; Faulk et al.

    2012; Ong et al. 2006). Overall, the direct effects of work

    stress and positive affect on burnout revealed a summative

    relationship between the two predictors, meaning that

    while high stress levels led to teacher burnout, positive

    affect had a restorative effect which reduced the accumu-

    lation of stress and prevented the precipitation of teacher

    burnout (Fredrickson 2000; Seery et al. 2010). From a

    theoretical standpoint, Fredrickson and colleagues refer to

    this process as the undoing effect of positive affect on

    the harmful consequences of stress (Fredrickson et al.

    2000; Fredrickson and Levenson 1998; Tugade and Fred-

    rickson 2004).

    Implications from the present study should be viewed in

    light of several limitations. First, the cross-sectional survey

    design of the study cannot determine directionality or

    temporality of associations between variables; as such, the

    resulting associations between variables may be true in

    reverse direction (e.g., perceived work stress predicts

    adaptation and/or adaptation predicts perceived work

    stress; positive affect predicts adaptation and/or adaptation

    predicts positive affect). It may also be possible that other

    confounding factors accounted for some of the observed

    relationships. Likewise, a prospective design would allow

  • for assessment of the stress levels teachers experience over

    the course of the academic year, as evidence suggests that

    it may vary (Travers and Cooper 1996). Second, the self-

    report nature of the survey instrument and voluntary par-

    ticipation may have influenced the results with inherent

    errors and biases, such as the potential for untruthful or

    inaccurate responses due to lack of self-awareness.

    Although the use of anonymous surveys enhanced the

    strength of the study, the response rate of 26 % was only

    moderate (Alreck and Settle 2004), and information was

    not available about non-respondents. Additionally, the

    snowball sampling procedure of asking initial participants

    to recruit five other teachers to complete the surveys may

    have resulted in a biased sample that may not be well-

    representative of the true teacher population. Our sample

    was comprised of experienced individuals with an average

    of 18 years of teaching, and 22 % were recipients of a

    prestigious Teaching Excellence Award. However, Duck-

    worth et al. (2009) found that positive traits predicted

    effectiveness in a sample of novice teachers; this previous

    work, coupled with the present study, suggests that positive

    affect may be beneficial to teachers across all levels of

    experience. Despite these limitations, the findings of this

    study offer important implications and provide support for

    the broaden-and-build theory of positive emotions as an

    effective theoretical framework for developing stress

    management programs, enhancing positive affect, and

    promoting resilience among public school teachers.
